    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 2 %@4]  
    #Z`q+@@ ]A  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: ,+vy,<e&  
    enableservice('AutomationServer', true) m=A(NKZ   
    enableservice('AutomationServer') ~tUl}  
    ," Wr"  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 iWB=sL&p

    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: k,E{C{^M  
    1. 在FRED脚本编辑界面找到参考. QP^Cx=  
    2. 找到Matlab Automation Server Type Library 3kIN~/<R+7  
    3. 将名字改为MLAPP 1s2>C!\

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 4Lh!8g=/

    1. 创建Matlab服务器。 #ASz;$P  
    2. 移动探测面对于前一聚焦面的位置。 Y1OkkcPb{  
    3. 在探测面追迹光线 *:YiimOY"

    6. 使用PutFullMatrix发送标量场数据到Matlab中 1i"WDu*h3
